(US4965105-A)      An insulation sleeve for a round galvanic primary cell comprises a coiled paper strip with an absorbent underside forming an inner tubular surface of said strip for absorbing electrolyte. A plastic coated upper side forms an outer tubular surface of the strip for sealing in said electrolyte and for shielding the absorbing layer. The strip has a first lengthwise edge folded over toward the underside such that siad edge overlaps and is adhesively bonded to a second unaltered lengthwise edge of the strip.    Pref. only one edge is folded over toward the under side and it is adhesively bonded to the unaltered edge by way of fused plastic coatings.    ADVANTAGE -   A number of strong anode sleeves may be cut from a single sleeve. (5pp)d    (EP319742-B1)      Insulating sleeve in a galvanic primary element in the form of a round cell, which insulating sleeve comprises a wound paper tape laminated on one side with plastics, characterised in that a paper web (3) having a plastics coating (4) on its upper side and a longitudinal edge (10) folded around endlessly downwards towards the underside is wound up with the elastics coating turned outwards such that the folded-around paper web longitudinal edge and the margin of the other side of the paper web overlap, with the folded-around paper longitudinal edge lying on the margin of the other side, and in that the paper web windings are bonded by way of the plastics coatings in the overlapping zone (14).    (DE3873702-G)      The insulating sleeve for a primary cell consists of a wound paper strip surfaced with a plastic material. One paper strip with a film covering on the upper side is wound with one edge folded round underneath, this folded edge overlaps then the edge of the other side during the winding process, and a secondpaper strip is bonded on underneath.    ADVANTAGE -   The insulation for the solvent electrode is produced by a simple wrapping method. Apart from providing good electrical insulation it also produces completely effective sealing against electrolyte.
